Embodiment Construction

[0021] Below in conjunction with embodiment, the present invention will be further described. The following description is by way of example, but the protection scope of the present invention is not limited thereto.

[0022] The self-aligning ball bearing motor of this embodiment is composed of a main stator core assembly 5, a rotor assembly, a front end bracket 3, a rear end bracket 13, a front end bearing, a tail end bearing, a self-radiating fan blade assembly and a load fan blade assembly constitute.

[0023] The front end bracket 3 and the tail end bracket 13 are all the same as the existing ones, and the bearing chamber is an inner conical surface, that is, one end facing the rotor 7 is larger and the other end is smaller.

[0024] The front end bearing is composed of the front end bearing sleeve 17 and the front end ball bearing 16, and the tail end bearing is composed of the tail end bearing sleeve 8 and the tail end ball bearing 9; the front end bearing sleeve 17 and...

Abstract

The invention discloses a ball bearing motor capable of adjusting the center automatically and relates to the technical field of micro motors. The ball bearing motor comprises a main stator core component 5, a rotor component, a front-end support 3, a tail-end support 13, a front-end bearing, a tail-end bearing, a self-heat-dissipation fan blade component and a load fan blade component. The ball bearing motor has the characteristics of simple structure, convenience in machining, low noise, long service life of ball bearings, good low-voltage startability, stable rotating speed, higher efficiency, capability of automatic center adjustment and the like. As a shaded pole type micro motor, the ball bearing motor is applied to equipment with higher rotating speeds, longer service lives and lower noise.

Description

technical field [0001] The invention relates to the technical field of micro motors, in particular to a self-aligning ball bearing motor. Background technique [0002] In the prior art, in the miniature ball bearing motor, the bearings at both ends are ball bearings. Due to its high speed, the concentricity of the ball bearings at both ends is required to be high, and the manufacturing precision of the brackets at both ends is required to be high, so that The manufacturing cost of the product is increased. Chinese Patent (Application No. 01220294964.8) "An Aligning Bracket for Fixing the Rotary Shaft of a Small Power Motor" includes a bracket (1). There is a through hole at the axis of the bracket, and a motor shaft (5 ) on the cup (2) shaped like an abacus bead, the outer side of the cup is wrapped with an oil cotton ring (4), and it also includes a gland (3) for pressing the cup into the through hole, the through hole The inner wall of the hole is divided into the first,...
